AM417 Ratiometric instrumentation amplifier with adjustable output stage PRINCIPLE FUNCTION Integrated instrumentation amplifier with an output stage for the amplification of differential signals and with an internal current source for the supply of external signal sources.
The output signal is a voltage between 0.5 and 4.5V, ratiometrical to the supply voltage.
The output span could be adjusted by the changeable gain of the output stage.
VCC = 5V 5% differential input voltage 0200mV
